SHOE-SEWING MACHINE.

SPECIFICATION forming part of Letters Patent No. 697,600, dated April 15 1902.

Application filed August 31,1900. Serial No. 28,650. (No model.)

To all wtmn/ it ntcty concern:

Be it known that I, EDWIN E. BEAN, a citi- Zen of the United, AStatesuresiding at Warner, in the county of `Merrimack and State of New Hampshire, have invented certain new and useful Improvements in Shoe-Sewing Machines, of whichthefollowing is a specification. y

This invention relates to certain improvements on the shoe-sewing machine described in my Patent No. 666,225, dated January l5, 1901.

My invention consists ef an automatic device for locking the clamp or presser-foot which engages the edge of the sole and resists the thrust of the needle, said clamp permitting me to dispense with the awl shown in the original application above referred to, and yet enabling the needle to penetrate a very thick between substance without difficulty. I have found in practice that the principal reason why Va very thick between substance cannot be penetrated Yby theneedle alone in thel prior machines which are now in general use is because the shoe is not positively held against slipping downA and a rm support'to resist the thrust of the needle is not provided substantially in line Y with its path. As the needle forces its way through the between substance it has a strong tendency to press down the shoe, and as this force is largely' resisted by the operator the result is that the needle passes .out of the work too high or is sprung outwardly or partially straightened. This soon causes the needle to get out of Ashape and become broken. When the support is below the path of the needle, the shoe is often slightly tipped in the hands of the operator with the same results,'and asa general rule theback-rest, which engages the shoe below the sole, has been relied'upon to support the shoe and resist the thrustA of the needle.

My improvements further consist in an improved'form of looper for placing the thread in the eye of the needle 'and in a presserringer which presses the upper into. its proper..

place when sewing around the shank of a shoe, so that there will be no possibility of the needle passing through the upper at any points other thanv the proper ones.

My improvements further consist in several other particulars hereinafter to be referred to.

For a more complete understanding of my invention reference is made to the accompanyingdrawings, in which- ,Figure 1 is a side elevation of the righthand side of the machine. y Fig. 2 is an enlarged side elevation of the right-hand side of the machine, showing the principal working parts thereof, a number vof the parts bef ing'removed, so as to show certain parts not shown in Fig. 1.' Fig. 2 is a cross-section on the line a a of Fig. 2. Fig. 3 is a side elevationof the left-hand side of the machine. Figs. 3 and 3" are detailed Views of the backrest lock, Fig. 3 being a cross-section on the line b bof Fig. 3b.

Fig. l0 is a front view of the channel-guide, showing the tension for the locking-thread. Fig. 11 is a detailed view of the measuring-finger. Fig. 12 is arfront view of the cast-off. Fig. 13 shows a side, end, and top view of the lasting-finger. Fig. 14 is a detailed sectional view on the line e e of Fig. 2. Fig. 15 is a top view of the feed-lever. Fig. 16 is a front view of the several parts carried by the needle-shaft. Figs. 17 and 18 show the two p0- sitions of the feed spur and clamp. Figs. 19, 20, 21, and 22 show severalof thepositions assumed by the parts during the operation of taking the stitch. Fig.,23 is a View of the stitch after it is completed.

The frame of the machine consists of a horizontal base-piece A, from the outer ends of which two supports A and A2 project upwardly and carry the main driving-shaft B, which rotates in bearings in the said supports. The cams L, J, C, D, G, F, H, I, and

IOO

the properconformation to transmit the desired motion to the several devices to which they are connected. The cam C is provided with a cam-groove M on its periphery in addition to the groove in its face. Two shafts B B2 are secured to the uprights A A2 above, parallel with, and equidistant from shaft B, the shaft B serving as a fulcrnm for levers D', F, l', and K', and B2 for levers Il', C', and J.

The mid-plate A2, which is secured to the base-piece A, is provided with a bracket A4 at its front end and radiators A2. The midplate is provided with a passage (see Fig. 4) which is connected to suitable passages in the bracket and radiators, an aperture A11 being provided in the mid-plate, (see Fig. 5,) to which a steam-pipe may be connected, so that all parts may be kept hot.

The bell-crank lever G', which is operated by cam G, is fulcrumed to the mid-plate A2 by stud g, which is secured therein. The needle-segment, g2, which carries the curved needle g4, having the hook on its side of shortest curvature, is secured to a short hollow sleeve g2, which projects from the left side thereof and is journaled in the lower end of the bracket-piece A4. (See dotted lines in Fig. 16.) The needle is oscillated by the eam G through the medium of lever G and connecting-rod g'.

The needle-guide segment e2 is secured to the shaft e' next the needle-segment, the larger end of said shaft being journaled in the bracket A4 inside the hollow sleeve g2 and the small end being jonrnaled in the bracketpiece A5, which is secured to the mid-plate A2. The larger end of the shaft e extends through the bracket A4 and has an arm e secured thereto, the hub of which is larger than the outside diameter of the sleeve g2 and serves as a guard to keep the needle-segment from sliding to the left on the shaft e. A spring e4 is secured at one end to the outer end of the arm e and at its opposite end to the bracket A4 and at all times tends to throw the arm forward and throw the needle-guide c2, which is secured to the segment e2, toward the point-of the needle. A stop-pin e2 in bracket A4 is adapted to engage arm e and limit the forward movement of the guide, and a stop-pin e7 is secured to the sleeve g2 and extends through the slot e2 in arm e and serves to limit the movement of the needleguide toward the point of the needle at all times, but permits it to engage the sole of the shoe in all positions of the latter while being sewed.

The feed-spurt" is secured to the side of segment 12 which is nearest to the needle-guide segment, and from its opposite side a hollow sleeve i2 projects, which is journaled on the small end of the shaft ef, the combined length of the segment I2 and its sleeve i2 being equal to the distance between the needle-guide segment e2 and the bracket A5 minus the length of the longest stitch required. The feed-spur segment I2 may therefore oscillate and slide laterally on the shaft e. The feed-spur z" has swinging and lateral movements on shaft e', its swinging movements being communicated to it from the cam I through the lever I', connecting-rod 12, and segment12, the connectingrod 12 being provided with universal joints to accommodate tho compound movements of the segment I2.

The feed-clamp K4 is rmly secured to the segment K2, and the latter is journaled on the sleeve i2 and is prevented from sliding laterally on the sleeve 2 by a tongue i4, which is secured to the segment K2 and engages an annular groove 712 in the annular sleeve z2.

The feed-clamp segment K2 is connected with the lever K by the universally-jointed connecting-rod K2, and the cam K is so formed as to give the clamp K4 two swinging forwardand-back movements during the process of taking the stitch, one of which is simultaneous with the forward -and back swinging movement of the feed-spur, so that they move simultan eously to ward and from each other on opposite sides of the between substance and clamp the material between them as they approach each other and release it as they recede. The otherforward-and-back movement of the clamp takes place while the needle draws in the needle-loop. The lateral movements of the spur and clamp are simultaneous, both being operated by the lever M, which engages the groove M in the cam C, said lever swinging on the vertical pivot m, the latter being supported on bracket A40. The front end of the lever M is pivoted to the link M2 by a screw m, said link passing through an aperture A0 in the mid-plate. The opposite end of link M2 is pivoted to a lever M2 by a screw m4, which is secured in the slot m5 of lever M2, said lever M2 being pivoted at its rear end on the screw m2, which is secured in the bracket A5. (See Figs. l, 3, and l5.) The forward end of lever Ma is provided with a vertical notch m2, (see Figs. l1 and 15,) which engages a tongue 797 on the segment K2. When the leverM is swung on its pivot, the lever M2 will be caused to swing on its pivot m2 and cause both segments K2 and l2 to slide on the shaft e'. The length of this lateral movement, and therefore the length of the stitch, will be adjusted by varying the position of the screw m4 in the slot m5, as will be obvious. The lower end of the clamp K4 is forked or cloven, (see Fig. 16,) so that the needle may pass directly between the forks of the clamp while it is holding the upper against the shoulder of the sole.

The rear end of the connecting-rod K2 is provided with a flange k2, which is located in a cup h5, the rear end of which is pivoted to the lever K. The front end of the cup is provided with a screw-plug 704, through which the rod K2 passes, and a spring 7a2 is interposed between said plug 7a4 and ilange 7a2. lVhen the lever K is thrown back to draw the clam p K4 against the upper and force the latter against vthe shoulder of the sole, the force IOS IIO

with which the clamp. will engage the upper will be determined bythe spring 7c3, which may be suitably adj usted by the plug 7a4. It will be obvious that the thickness of the between substance will vary in different portions of theparts to besewed on account of the interposition of the counter andtoecap and on account of the fact that some qualities of stockl are more compressible than others.

Although the clamp K4 is in somewhat different positions when dierent stitches are taken, thel feed-spur always being brought to f the same position, the upper will always be engaged with substantially the same force. This force, however, should not be excessive, asit would pinch-the between substance too 'much and drive thefeed-spur into the chanclamp K4 after it has reached its proper po-k sition, sothat the clampvwill be firmly held in any-operative position which it may assume, will forma perfectly solidresistance tothe thrust of the needle, and will clamp the between substance so firmly that the shoe cannot slipv down. This locking device consists, essentially, of a latch O3, which is pivoted at its upper end on the pin O4'and'is provided with an inclined face at itsrlower end. An inclined shoulder 7n5is also provided on theclamp-segment K3. Abell-crank lever O is pivoted on the take-up shaft J4 and is provided vwith a cam-slot O at its rear end.

This cam-slot is engaged by a pin O5,- which, is secured in the ylower end of the lever M',

which operates the looper, as hereinafter set forth. A rod O2 is pivoted to the latch O3 at its forward end andv its-rear end passes to the upper end of the bell-crank lever O. .A spring o is located on said r'odO2 between the bellcrank `lever and a suitable stop OQandchecknuts 02 arelo'cated on the rear part of the rod Of-and engage the rear side of the lever O. When the lever F' is swung forward,the horizontal portion of the lever O will be lifted and the vertical portion'thrown forward, so that Vthe latch O3 will berswungl forward, causing its lower end to engage the shoulder k6. The

force-with which the latch is thrown against the shoulder will be determined by the ten-4 sion ofthe spring 0, which needs onlyv to be very light.

Inoperation the clamp K4 is first brought against the-upper. with a force equal to theV tension of the spring 7a3, and assoon as it has reached its proper position the latch will be thrown forward, so y that the lower inclined end thereof comes -tightly into contact with the shoulder k6, as shown in Figi?. W'hen the needle advances to penetrate the stock, it willbe `obvious that substantially the whole force which is necessary to resist ythe thrust ofthe needle is taken upby the latch O3, and as the pivot O4 of the latch is placed so that it cornes substantially in line with the line of force acting onthe end ofthe latch no strain will be thrown on the spring o and the clamp will be held so that the spring k3 cannot be further compressed. A perfectly solid resistance is thus provided to oppose the thrust of the needle, whichis substantially in line with the path/thereof, the two prongs of the clamp K4 engaging theupper/on eachvside of ;the needle and at the same levelas the point where the needlepasses through thework. There is therefore notendency to shiftthe shoe in the hands of the operator or possibility of the clamps being thrown back by the pressurev of the. needle. and separating. the clamp and spur, so that the shoe may slip down and cause the needle to bend outside its proper arc and pass through Vthe between substance in a direction other thanthat desired. The pivot of the latch is so located with respect `to the center on which the clamp is swung and to the shoulder k6 that the latter moves away from the pivot as it isadvanced, and the engaging end of the latch is inclined with respect tov a radius drawn thereto from the center of the pivot. YThe engaging surfaces of the shoulder and latch may therefore come into solid engagement within a range of positions which is -amplys'uicient for the purpose. The clamp will therefore be locked in whatever position itmay assume,so that it is immaterialA wheth er the between substance be thick` Or-thin.

The usual and'most desirable way of fitting the sole of a turno'r welt shoe preparatory fto machine-sewing is to cut a rabbetin the edge IOO IIO

thereof, .leaving a vertical shoulderyagainst i which theY clamp presses-.the upper, and a horizontally-proj ecting iiange, directly above which theneedle emerges. In lasting a shoe it is difficult to draw the upper tightly against the last at the shank of theishoesothat it will fit the last closelyandwill be drawn down tight on this iiange of the sole even after-the upperfhas been pressed Yin bythe-clamp K4. In sewing this portion of the shoe it is necessary to tip the last so thattheportion of the upper next the edge .of the sole is nearly horizontal. For this reason there has been great difficulty-experienced in causing the needle to pass outthrough the upper at the proper point, .it oftenV happening, that the needle passes out through the upper below the point at which it should,lthus badly injuring the shoe. To prevent this occurrence and to provide amcans for vforcing theupper.- down on the iiange of the sole and.k holding it in its properposition to receivethepoint ofthe nee-V dle, I have provided what I term a presser.-`

finger, which engages the upper directly below the end of the clamp K4. The mechanism which comprises this portion of my invention consists of a slide S, which is connected at its rear end to the lever F by a bolt s. The forward end of the slide is provided with a slightly-inclined slot s, through which a screw s2 passes and is secured in the midplate A3. The bolt s is provided with an enlarged head on its inner side and passes through an elongated slot si". (Shown in dotted lines in Fig. 2 and in section in Fig. 2.) A spring-washer s4 of any suitable form is provided between the nut on the outer end of the bolts and the lever F', through which the bolt passes. The lever F is provided with enlargements S8 on the front and rear sides thereof directly opposite the end of the slot through which the bolt s passes. A spring s3 is secured to the rear side of lever F and rests at its lower end on the rear enlargement SS. An angular' bracket Fois secured to or cast with the lever F and is provided with an adjusting-screw s", which engages the rear side of the spring .s3 at an intermediate portion thereof, so as to reinforce the spring and give it the desired tension. The bottom portion of the spring s3 is of sufficient width to extend beyond the edge of the lever F and engage the end ofthe slide S in certain positions of the latter. (See Fig. 21.) The nut on the bolt s is tightened, so as to give the desired frictional connection between the lever F and the slide S. The front of the slide S is provided with a forwardly-extending finger S', which is curved upwardly at the intermedi- 1 ate portion to permit the last to be swung upwardly while sewing the shoe, and the forward end thereof is provided with a notch s6, which is directly in line with the path of the needle and of sufficient width to permit the needle to pass therein. (See Fig. 13.) The front edge of the finger is made comparatively sharp, and the inclined surface on the upper side thereof corresponds, substantiall y, to the inclined surface at the bottom of clamp K4, so that when the finger is pressed forward these two surfaces will come into close engagement. The particular form of the end of this finger is not wholly essential; but it is preferably made inclined on both upper and under sides, so that they meet in a comparatively sharp edge, as shown in Fig. 13, although it may be made inclined on the upper side only with almost equal advantage. The looper FG is also operated by the lever F', so that it will be observed that the latch O3 and the presser-finger S will both be advanced at the same time the looper is advanced to thread the needle and after the clamp K4 has come into engagement and fed along the shoe. Then the lever F begins its forward movement, the slide S will be in its rear position opposite to that shown in Fig. 2 and will then be carried forward by the frictional engagement of the head of the bolt s and the side of the lever F therewith, and

as the slide is moved forward it will be lowered slightly on account of the inclination of the slot s, the inclined upper surface at the end of the fingerengaging the inclined lower end of the clamp and the under side of the finger pressing the upper down on the iiange of the sole and holding the same in its proper position. (See Fig. 17.) After the end of the finger has been forced into contact with the upper and has pressed it into place the,

finger can no longer be advanced, and therefore the bolt s will slide in the slot S5 until the end of the slide engages the spring s3. When the slide and spring come into contact, as shown in Fig. 2, the spring will be forced rearwardly by the slide, so that the force with which the end of the finger presses the upper against the sole will be determined by the tension of the spring .s3 plus the force of the frictionalengagement between the slide and lever F. This tension is suiicient to press down the upper into place and hold it while the needle is passing therethrough. It will be observed that this presser-finger is of no particular advantage, except when sewing those portions of the shoe in which the angle between the bottom and side of the last closely approaches one hundred and eighty degrees and therefore holds the upper nearly in line with the direction of movement of the point of the needle as it passes through the upper, as in the shank of the shoe. In sewing these portions of the shoe it is, however, of great importance, and the danger of the needle passing through the upper at points other than that which it is intended to pass is wholly avoided.

The looper is construct-ed and operates substantially the same as shown and described in the prior application above referred to, with the single exception now to be referred to.

In my prior machine, above referred to, considerable difficulty was experienced in causing the looper at all times to place the thread in the needle-hook, as it was necessary to have the threadmeasuring finger draw the thread away from the shoe, so that the thread was drawn in a diagonal direction by the looper as it was laid in the needlehook. I therefore provide the inner side of the swingingleve1F5,which carriesthe threadguidef, with a forwardly-projecting finger F7, (see Figs. 3 and 7,) which is nearly as far toward the front as the end of the threadguide f7.

The thread-finger Z5 is secured to the shaft d* and operated by the cam D through the medium of the lever D', connecting-rod d, and crank-arm d. The right-hand side of the shaft d4 is provided with an annular groove di, and the front end of the feed-lever M3 is provided with a bracket mi", which engages said groove L17, as shown in Fig. 1l. The shaft d4 is journalcd in mid-plate A3 and is adapted to slide back and forth therein. When the take-up is thrown back so as to take up the thread and set the stitch about the locking- IIO loop and while the thread-gnidef7 is in its 'rearmost position, as shown in Fig. 22, the feed-spur and feed-clamp are thrown out of engagement with the work and lnoved to the right by the lever M3, so as to engage the shoe at a more advanced point. As they are moved to the right the shaft d4 is also moved to the right, so that the end of the thread-finger d5 is carried to the right of the thread leading from the stitch whichy has just been formed to the guidef7, as shown in dotted lines in Fig. '7. The thread-nger is then thrown down, so that its end is at the right of the thread, and its shoulder d6 engages the upper side thereof and draws it down, so that it is held in a notch formed in the lower end thereof. Vhen the lever M3 is thrown to the left to feed along the shoe, the shaft d4 will also be moved to the left, and-the thread-finger will be carried to thepositionshown in full lines in Fig. v7. The looper thenadvances,

following the dotted line Z, (shownin Fig. 7,)

inthe direction of the arrow, and as it advances the thread will be carried into the notch in the end of the finger F7, so that the portion of the thread which runs from Vthe end of the guide f7 to lhe'notch in theend of iinger F7 will be held nearly -at right angles to the path of theueedle. As the lever F6 is swung down guidef7 passes on one side of the needle andv finger F7 on the other, as indicated in Fig. '7,V so that the thread willbe laid securely in the needle-hook and all possibility of the needle not being properly threaded is avoided. Afterthe thread has been laid in the needle-hook the'need'le retreatsand draws the loop through the work. At the sam etime the thread-measuringfinger is swung upward and the take-up advanced,so that slack thread :is provided on each side of the needle, as explained in the previous patent above referred to.

The rear side of the east-off Q is provided with an inwardly-projecting pin Q7. (See Figs. l, 2, 3, and 12.) In operation after the needle has advanced and the thread been placed therein, as shown in Fig. 19, and the loop drawn through the work (shown in Fig. 20) and the needle drawn back to its fullest extent the cast-off is swung forward, so that the aperture g5 therein coincides with the path of the needle.` The needle is then-advanced through the aperture g5 in the cast-off and casts off the needle-loop. As the needle-guide is constantly drawn forward by the spring e4 and held close tothe hook of the needle it would prevent the loop being cast off if means were not provided to hold it away fromthe Yhook of the needle during the cast-off operai tion; As the needle is advancing to pass through the cast-off the pin q7'on the cast-off will engage the under side of the needle-guide and hold it away from the needle-loop, as shown in Fig. 2l', so that it will not interfere with the operation off-casting off the loop.

It is desirable that the locking-thread W be placed under a slight degree of tension, and

to provide this tension I employ the means shown in Figs. l and 10, which consists of a Hat spring n3, which is secured to the arm N by screw ns. The end of said spring is provided with an aperture which is slightly out of line with the aperture in the channel-guide N, through which the thread W passes, and the end of said springr is normally held slightly above the arm N When the-thread is drawn through the holes, there is a slight tendency to draw down the spring, which places the thread Vunder a certain amount of tension. This tension may be increased by tightening the screw n4.'

The operation of the machine is the same in every other particular as that disclosed in the prior patent above referred to, the locking-loop being drawn through the needle-loop and the needle-loop drawn about the locking- .'loop, as therein disclosed. A detailed description thereof'is therefore deemed unnecessary.
